<div class="method">
    <code class="details" id="batchGet">batchGet(database, body=None, x__xgafv=None)</code>
  <pre>Gets multiple documents.

Documents returned by this method are not guaranteed to be returned in the
same order that they were requested.

Args:
  database: string, Required. The database name. In the format:
`projects/{project_id}/databases/{database_id}`. (required)
  body: object, The request body.
    The object takes the form of:

{ # The request for Firestore.BatchGetDocuments.
    &quot;documents&quot;: [ # The names of the documents to retrieve. In the format:
        # `projects/{project_id}/databases/{database_id}/documents/{document_path}`.
        # The request will fail if any of the document is not a child resource of the
        # given `database`. Duplicate names will be elided.
      &quot;A String&quot;,
    ],
    &quot;readTime&quot;: &quot;A String&quot;, # Reads documents as they were at the given time.
        # This may not be older than 270 seconds.
    &quot;newTransaction&quot;: { # Options for creating a new transaction. # Starts a new transaction and reads the documents.
        # Defaults to a read-only transaction.
        # The new transaction ID will be returned as the first response in the
        # stream.
      &quot;readOnly&quot;: { # Options for a transaction that can only be used to read documents. # The transaction can only be used for read operations.
        &quot;readTime&quot;: &quot;A String&quot;, # Reads documents at the given time.
            # This may not be older than 60 seconds.
      },

      },
    },
    &quot;mask&quot;: { # A set of field paths on a document. # The fields to return. If not set, returns all fields.
        # 
        # If a document has a field that is not present in this mask, that field will
        # not be returned in the response.
        # Used to restrict a get or update operation on a document to a subset of its
        # fields.
        # This is different from standard field masks, as this is always scoped to a
        # Document, and takes in account the dynamic nature of Value.
      &quot;fieldPaths&quot;: [ # The list of field paths in the mask. See Document.fields for a field
          # path syntax reference.

<div class="method">
    <code class="details" id="batchWrite">batchWrite(database, body=None, x__xgafv=None)</code>
